CREAMER In-Weg seals are designed for the internal sealing of leaking pipe joints in all types of pipe, including cast iron, ductile iron, concrete, reinforced concrete, steel, vitrified clay, and plastic piping systems with diameters of 16 in. or larger. The seals are designed to permanently eliminate leaks at internal pressures up to 300 psi. Excavations for access can be as much as 5,000 ft. apart, causing very little disruption to traffic.

A range of seal widths is available for use on a variety of joint gaps. The seals are locked into place by carbon steel, stainless steel, or composite retaining bands depending on the applications. The seals can also be used in conjunction with specially manufactured sleeves to permanently repair cracks, reducers, complete pipe lengths, or even seal off disused branches and service connections.

A non-toxic EPDM (ethylene propylene diene monomer) synthetic rubber compound is used to manufacture seals for potable water, raw water, and sewage pipe applications. The stainless steel retaining bands are made from the appropriate alloy for each particular application.
